A method for operating an electronic device is provided. The method includes monitoring a noise level of a noise signal received via a panel while wireless power is transmitted and/or received at a first power level via at least a conductive pattern, and generating a signal for changing the first power level corresponding to at least a part of an input to at least a part of the panel.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An electronic device comprising: a panel configured to detect a change of an external magnetic field; a wireless power circuit; a conductive pattern electrically connected to the wireless power circuit; a processor electrically connected to the panel and to the wireless power circuit; and a memory electrically connected to the processor, wherein the memory stores instructions for instructing, when being executed, the processor to: monitor a noise level of a noise signal, which is generated by an input that is received via the panel, while wireless power is transmitted and/or received at a first power level through the conductive pattern, and generate a signal for changing the first power level to a second power level, which is less than the first power level, based on a location of the input on the panel to reduce interference from the wireless power being transferred at the location of the input.
2. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to maintain an intensity of a wireless charging current so that wireless charging of the first power level is performed if the noise level is lower than a specified value.
3. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to lower an intensity of a wireless charging current so that wireless charging of the second power level, which is less than the first power level, is performed if the noise level is higher than a specified value.
4. The electronic device of claim 3 , further comprising: a plurality of wireless power antennas configured to receive the wireless power; and a switch configured to select at least one of the plurality of wireless power antennas, wherein the memory stores instructions for instructing, when being executed, the processor to select at least a portion of the plurality of wireless power antennas by controlling the switch to reduce an antenna size for transmitting/receiving the wireless power.
5. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to perform a wireless charging of a specified power level corresponding to the noise level.
6. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to transmit a signal for requesting adjustment of a wireless charging current to a wireless charging device.
7. The electronic device of claim 6 , wherein the memory stores instructions for instructing, when being executed, the processor to transmit, to the wireless charging device, at least one of a signal for requesting reduction of transmission power, a signal for requesting reduction of a size of a transmitter coil, or a signal for requesting a change of a transmission frequency.
8. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to output guide information for changing a charging current if an input occurs on a panel area from which a noise of a specified noise level or higher is measured.
9. The electronic device of claim 8 , wherein the memory stores instructions for instructing, when being executed, the processor to display the guide information on a location of the input or an adjacent area thereto.
10. The electronic device of claim 1 , wherein the memory stores instructions for instructing, when being executed, the processor to output an alarm about a state of arrangement of the electronic device and a wireless charging device on a basis of a distribution state of the noise level.
11. A method for operating an electronic device, the method comprising: monitoring, by the electronic device, a noise level of a noise signal, which is generated by an input that is received via a panel, while wireless power is transmitted and/or received at a first power level through a conductive pattern; and generating, by the electronic device, a signal for changing the first power level to a second power level, which is less than the first power level, based on a location of the input from on the panel to reduce interference from the wireless power being transferred at the location of the input.
12. The method of claim 11 , wherein the generating comprises maintaining a wireless charging state of the first power level if the noise level is lower than a specified value.
13. The method of claim 11 , wherein the generating comprises reducing an intensity of a wireless charging current so that wireless charging corresponding to the second power level different from the first power level is performed if the noise level is higher than a specified value.
14. The method of claim 13 , wherein the reducing comprises reducing a size of a wireless power antenna.
15. The method of claim 11 , wherein the generating comprises collecting a wireless charging current of a specified intensity according to the noise level.
16. The method of claim 11 , wherein the generating comprises transmitting, to a wireless charging device, a signal for requesting adjustment of a wireless charging current.
17. The method of claim 16 , wherein the transmitting of the signal to the wireless charging device comprises transmitting, to the wireless charging device, at least one of a signal for requesting reduction of transmission power, a signal for requesting reduction of an area of a transmitter coil, or a signal for requesting a change of a transmission frequency.
18. The method of claim 11 , further comprising: outputting guide information for changing a charging current if an input occurs on a panel area from which a noise of a specified noise level or higher is measured.
19. The method of claim 18 , wherein the outputting comprises displaying the guide information on a location of the input or an adjacent area thereto.
20. The method of claim 11 , further comprising: outputting an alarm about a state of arrangement of the electronic device and a wireless charging device according to a distribution state of the noise level.
